Diagnose the acid base disturbance. How do you know (i.e. is pHalkaline or acidic, is pCO2 alkaline or acidic, is bicarb alkalineor acidic) (3 POINTS)? What is likely the cause of this imbalance,why? How would the respiratory system compensate for this imbalance(2 POINTS)? How would the urinary system compensate for thisimbalance.
2. What is the glomerular filtration rate (GFR)? How does theGFR relate to net filtration pressure? What are 2 physiologicalmechanisms that can change the GFR, briefly explain how they affectthe GFR? Identify a hormone that will increase the GFR. Identify ahormone that will decrease the GFR .
